The relationship between clinical disability and quantitative susceptibility values in the putamen and thalamus across PPMS and RRMS groups. X-axes indicate EDSS, while y-axes indicate quantitative susceptibility values in parts per billion. A positive correlation between EDSS and putaminal quantitative susceptibility values is present in both the RRMS (A) and PPMS (B) groups. In the thalamus, a negative correlation between EDSS and quantitative susceptibility is present only in the RRMS group (C), while no correlation is observed in the PPMS group (D).

↵a The number of participants and the female/male ratio are reported for each group. Unless otherwise indicated, data are reported as mean (SD). Numbers in parentheses in the headers of columns 2–5 are No. of subjects in groups (F/M).
